Problems solved by technology

[0002] For the convenience of carrying, gift boxes and small and medium-sized packaging boxes usually have a handbag on the box. Most of the current handbags are made of single-layer plastic injection molding. Although the plastic handbag has high strength, it feels stiff and poor in comfort. A handbag made of PE and PET glued together. This kind of handbag has good hand feeling and strong toughness. However, due to the use of glue, it is easy to delaminate in high temperature weather or when it is heated, making the appearance fuzzy, unsightly and reducing Strength, most of the common handbags on the market are made of non-woven fabrics. Non-woven handbags are made of non-woven fabrics. Easy to decompose, non-toxic and non-irritating, rich in color, low in price, recyclable, etc.
[0003] However, for the non-woven fabrics on the market, in order to ensure the strength of the cloth belt, the thickness of the non-woven fabric is usually thicker, which will also cause the non-woven fabric bag to become thick and heavy, with poor hand feeling and unsightly appearance. Printing on the non-woven fabric bag Due to the rough surface of the pattern, the printing effect is poor. Therefore, in order to achieve the required strength and improve the handle of the non-woven bag under the premise of ensuring the light and thin performance of the non-woven bag, a new solution needs to be proposed to solve the problem. this problem

Embodiment 2

[0050] Embodiment 2: The difference from Embodiment 1 is that in step S1, PET / PET is selected, and the temperature of the hot rolling mill in step S5 is 110°C, which can produce a fabric with a hard hand, light and high strength, which is suitable for passing super Sonic stitching, and since the melting point of PET is 110°C, the temperature of the hot rolling mill is controlled at 110°C to ensure that PET / PER can be melted and bonded during hot rolling.

Embodiment 3

[0051] Embodiment three: the difference with embodiment one is: select PET / PP in step S1, wherein PET weight ratio is 70%-90%, PP weight ratio is 10%-30%, the temperature of hot rolling mill is 150°C, choose PET / PP composite material for mixed laying, and the PP weight accounts for 10%-30%, the produced fabric is PET on one side and PP on the other side. When making a packaging bag, the material is One side of the PP is in contact with each other, and heat sealing can be achieved through a sealing machine, and the heat-sealed packaging bag has a firm structure and is not easy to damage. The melting point of PP is 150°C, so when the cloth enters the hot rolling machine at 150°C, PP melts and the other The fibers are bonded into sheets.

Embodiment 4

[0052] Embodiment four: the difference with embodiment one is: select PET / PERPE in the step S1, wherein the weight ratio of PET is 70%-90%, the weight ratio of PETPE is 10%-30%, the hot rolling mill The temperature is 130°C, PETPE has a skin-core structure, the outer layer is PE with a lower melting point, and the inner layer is PET with a higher melting point, so that the melted PE can be used as an adhesive to bond and connect the fibers; the melting point of PE When the cotton web enters the hot rolling mill at 130°C, PE melts and acts as a binder to bond the fibers into a sheet of fabric without adding other binders, thereby realizing the lightweight of the fabric and making the fabric Thinner.

Abstract

The invention discloses a light and high-strength non-woven fabric production process and aims to solve the problem that traditional non-woven fabric is thick and not enough in strength. According tothe technical scheme, the process mainly includes the following steps of opening, cotton blending, carding, cross lapping, drawing, shaping, cloth storage, rolling and slitting; cross lapping includesthe step that a cotton web is sent from a first carding machine to a lapping machine, the discharge direction of the lapping machine is perpendicular to the feeding direction of the lapping machine,and the web sent from a cross lapping machine is a web having cross texture. According to the light and high-strength non-woven fabric production process, the produced non-woven fabric has the advantages of being light and uniform in strength, meanwhile reinforcement is conducted in the longitudinal direction, and the process is widely applied to packaging and other fields.
